Abstract

The good performance of a clock generator circuit in the power supply for triger TTL IC is very influential on the success of the lab. A series. Therefore, the effectiveness of use must be adapted to its use in the practicum. To create a clock generator circuit as a source of pulses from a digital counter IC, a timer IC can be used. This pulse generator or clock generator can be used for clock sources in making counters up and down. Clock generators are often referred to as clock generators. The pulse generator in making the circuit is often used linear integrated circuit (IC: Integrated Circuit). A linear IC that is commonly used in general is usually the NE555 which is a timer IC. As a timer it can also be used analogically as a Clock Generator or pulse generator which can generally generate the frequency or time as needed.

Abstract

Penelitian ini bertujuan mengatasi masalah ketidakstabilan sinyal dan kerusakan power supply pembangkit pulsa clock persegi di Laboratorium Elektronika Digital yang menyebabkan switch bouncing serta membuang waktu praktikum. Menggunakan metode Research and Development (R&D) model Borg dan Gall yang disederhanakan, dilakukan peremajaan (retrofitting) dengan mengintegrasikan modul astable multivibrator (IC NE555) dan Schmitt Trigger (IC 74LS13) sebagai anti-bouncing. Hasil pengujian osiloskop menunjukkan sinyal stabil (5,0 V, 49,9 Hz) dan bebas cacat (zero defect, bouncing teredam menjadi 0 ms). Efisiensi waktu persiapan meningkat dari 10 menit menjadi 2 menit, serta tingkat keberhasilan praktikum naik dari 40% menjadi 95%. Evaluasi kualitas layanan menggunakan metode SERVPERF terhadap 27 responden mahasiswa memperoleh skor rata-rata 4,46 dari 5,00 (Tingkat Pencapaian Responden 89,24%, kategori Sangat Memuaskan). Inovasi ini terbukti efektif mengoptimalkan keandalan fasilitas laboratorium.
